In this paper, a joint method to estimate unwrapped interferometric phase and alleviate the channel mismatch based on the multibaseline SAR interferometry system is presented. The calibration method proposed herein estimates the second order moments of phase vector from a set of received echo data. These theoretical analysis, supplemented with experimental results show that the method can effectively...
With multisatellite radar systems, several additional features are achieved: multistatic observation, interferometry, ground moving target indication (GMTI). In this letter, a new reduced-dimensional method based on joint pixels sum-difference (Sigma-Delta) data for clutter rejection and GMTI is proposed. The reduced-dimensional joint pixels Sigma-Delta data are obtained by the orthogonal projection...
